Late Birth and Reduced Risk of Womb Cancer

A breakthrough fact about the uterine
cancer
has come into light from a study conducted by the University of Southern
California. The researchers have found that women
who give last birth at the age of 40 may have a decreased risk of endometrial
cancer by 44 % than the women who delivered their last baby at the age of 25.

Late Birth and Reduced Risk of Womb Cancer

Uterine cancer or endometrial cancer is
the cancer that affects the endometrium i.e. the lining of the uterus (womb).
Endometrial cancer is the most common gynecological cancer in the United States
affecting around 50,000 women each year. The American Cancer Society has
estimated that 47,130 new cases of uterine body cancer will be diagnosed in
2012, out of which 8,010 women are believed to die from such cancers. Most of
these cases are endometrial cancer.

Wendy
Setiawan, professor of preventive medicine in the Keck School Of Medicine,
University of Southern California states that the protection from the uterine
cancer persists for many years in women who had their last delivery at their
30s and 40s.

This
research was carried out by examining 8,671 cases of endometrial cancer and a
total of 16,562 as control subjects. The cases were derived from the
Epidemiology of Endometrial Cancer Consortium. The researchers found that as
compared to women who last gave birth before 25-years, women who have their
last child between 30-34 years reduce their risk of uterine cancer by 17% and
those who have their last child between 30-34 years reduce their risk by 32%.
This miraculous effect was seen in women even as they aged.

Setiawan
says that the lower risk of cancer continued in older mothers at different
age-at-diagnosis group, including under the ages 50, 50-59, 60-69 and over 70,
which shows that the protection persists for many years.

However,
the researchers are not sure about the link between late pregnancy and uterine
cancers. In the view of Wendy Setiawan, the hormones secreted during the
pregnancy are beneficial in preventing cancer. These hormones may be helpful to
prevent the cancer-causing cells or they might develop a comparatively healthy
uterus during their late pregnancy.

According
to records, the number of cases of endometrial cancer is more comparatively
higher in the western countries than in the other parts of the world. According
to Indian Council of Medical Research (ICMR), 4.3/100,000 cases of uterine
cancer are reported in India every year and this number is believed to be on a
rise due to obesity and increased body weight.
